manipulating tags in multiple selections takes endlessly

[dieterdreist]

like the title suggests: I make a search for a certain tag: result is there in milliseconds. Delete the tag they have in common: takes 10-20 seconds for ca. 100 objects. Add a new tag to all of them (100 occurences): again endlessly.

You can try r2474, it should be a bit faster. There is also another bug, that keeps RelationListDialog running after layer has been removed. If you often remove data layer and then loads another data then tag operations might slow down.

With r2484 RelationListDialog responds faster to tag change events.

I can now set a new tag on hunders of objects in acceptable time (1-3s).

Closing as fixed.
